     11Downloading data in JOSM follows these 3 simple steps:
     121. Choose a source server and optional adjust the download options the server offers
     131. Choose an area to download
     141. Click on [[Image(source:trunk/images/download.png,middle)]] Download

    12 == Type of Data ==
    13 Different types of data can be downloaded:
     16
     17== Source server and download options of the server ==
     18By default there is only one source, the main OSM server. If [ExpertMode expert mode] is enabled then you have access to download data from Overpass API. (More servers may be added in the future.) Each server has its own special download options, which are explained below.
     19
     20=== Download from OSM ===
     21Different types of data can be downloaded (it is possible to download all three types at once):
    1422
    1523* [[osmwiki:Downloading data|OSM data]] ([[osmwiki:Elements|nodes, ways, relations]])
    … …  
    1725* [[Help/Dialog/Notes|OSM notes]]
    1826
    19 The type is chosen with the checkboxes at the top of the window. (It is possible to download all three types at once).
     27There might be a red warning below the data type check boxes displayed if the selected area is probably too large for the server and will be answered with an error message.[[BR]]
     28You can download bigger areas using several smaller ones.

     30=== Download from Overpass API ===

    2135== Area to download ==
    22 The dialog has multiple tabs. The exact configuration of tabs may be dependent on plugins you have installed, but you will generally at least have the following five.
     36Additional to the server choose you need to select in which area ("bounding box", "bbox") you want to download the data. The dialog has multiple tabs.
    2337
    24 When switching between tabs, the area shown in each tab will be the same. So if you select a bookmark for example and switch to the slippy map tab, the area of that bookmark is shown.
    25 
    26 **Note**: When the download dialog is called up with data already loaded, all fields are set to the currently visible bounding box. Thus a common use scenario is to first load your GPS track from a GPX file, then zoom the view so that the portion you wish to work on is fully visible, and then call up the download dialog which will reflect the visible area.
     38The Slippy map tab is the most intuitive one as you can simply choose the bbox with your mouse. If you change the bbox in another tab and go back to the Slippy map it will display the new bbox, so you can adjust it before downloading. When the download dialog is called up with data already loaded, the bbox of the downloaded window will be the same like your current [MapView map view].

    2840=== Slippy map ===
    2941[[Image(download_dialog.2.png,300px,right)]]
    30 The ''Slippy map'' provides a movable map like on the OSM front page with which you can interactively select the area to download. Only differences are that {{{Shift+Click}}} to zoom is not available, move the map the JOSM way by press and hold the right mouse button and select an area by press and hold the left mouse button.

     44Clicking on the [[Image(source:/trunk/images/layer-switcher-maximize.png,20,middle)]] button on the upper right gives you the option to change the displayed map for this window. The available maps are based on your [[Help/Preferences/Imagery|Imagery preferences]].

    55 == Area too large ==
    56 
    57 There might be a red warning at the bottom right displayed if the selected area is probably too large for the server and will be answered with an error message.[[BR]]
    58 You can download bigger areas using several smaller ones.
    59 
    60 
    61 == Layer control ==
    62 You can control whether the data is loaded into the current or in a new layer with the checkbox in the bottom left corner of the window:
    63 * if **Download as new layer** is selected, the data is loaded in a new layer
    64 * if **Download as new layer** is not selected, the data is loaded in the current data layer
    65 
    66 If there isn't any data layer yet, a new data layer is always created.
    67 
    68 
    69 == Display ==
    70 Clicking on the [[Image(source:/trunk/images/layer-switcher-maximize.png,20,middle)]] button on the upper right gives you the option to change the displayed map (rendering machine) for this window. The available maps are based on your [[Help/Preferences/Imagery|Imagery preferences]].
    71 
    72 An example of the displayed selection:
    73 
    74 * OpenStreetMap (Mapnik)
    75 * Cyclemap
    76 * Bing Aerial Maps
    77 * MapQuest Open Aerial
    78 
     69== JOSM download options ==
     70JOSM offers some general options of this download window:
     71 Download as new layer::
     72  If checked, the data is loaded in a new layer, if not selected, the data is loaded in the current data layer. (If there isn't any data layer yet, a new data layer is always created.)
     73 Open this dialog on startup::
     74  If checked this window will automatically be opened after the start of JOSM.
     75 Zoom to downloaded data::
     76  If checked the map view will move to the downloaded data after downloading, if not checked it will stay at its current position.
